New Jerusalem is a flying city that since its decent from Heaven when JESUS Christ returned didn't even once touch this earth, not even throughout the entire duration of the Millennial Reign of JESUS Christ.

Only when the LORD makes all things new, a new Heaven and a new Earth, then will New Jerusalem land for this earth on which we walk was cursed by GOD so a new one must be made in the likeness of that which was intended for Adam in the Garden of Eden to inhabit New Jerusalem for all of eternity.
